Solar Power Inverter Introduction

Off grid solar inverter is the lastest model presented by Zhejiang Eifesun Energy Technology Co.,Ltd. This off grid inverters have achieved significant improvements on Battery charging, AC transfer, etc. By adopting DIP (Dual In-line Package) switch, the EPVF provide more smart options for users to customize the performance of the device.


On Inverter

(1)High overload ability

(2)Low voltage trip selectable(9.5V/10V or 10V/10.5V), extracting max power from various batteries with different protections

(3)Low quiescent current, power saver mode to reduce power consumption to 10W(3s sensing cycle)/3W(30s sensing cycle)*

On Battery charger

(1)3-step intelligent battery charging

(2)8 pre set battery type selector plus de-sulphation for totally flat batteries

(3)Powerful charge rate up to 70Amp** ,selectable from 0%-100%

(4)PFC(Power Factor Correction) for charger, less power consumption than conventional units

On Transfer

(1)8 ms typical transfer time between battery and AC, guarantees power continuity

(2)15s delay before transfer when AC resumes, extra protection for loads when used with generator

(3)Input AC voltage range selectable(184-253V or 154-253V), for different kinds of loads

(4)30A/40A through current ability

(5)Allows start up and through power without batteries

(6)Output voltage regulation optional(230V/120V±10%)***

On Remote control & other features

(1)Ability to switch the unit on/off , select/deselect power saver mode

(2)17 alarms/warnings, informative for easier operation and trouble-shooting 

(3)LCD status display available

(4)Battery/AC priority switch available for off grid solar/wind system

(5)USB communication port available

(6)Solar charger controller available
